Yes. If pm-utils sees that there is a drm fb, then it will skip running any quirks itself. The idea is that if you're using kms, then it will properly handle suspend and resume. Do you still have /sys/class/drm/card0/device/graphics/fb0 when you boot with nomodeset? You can probably get a better idea what's going on you can run "PM_DEBUG=true pm-suspend" and look at /var/log/pm-suspend.log. -- Dan _______________________________________________ Pm-utils mailing list Pm-utils@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/pm-utils
